The volume of the smaller figure is 256 in³.
Given, the surface area of two figures are 16 and 25.
volume of the larger figure is 500.
volume of smaller figure =?
Similar figures have a scale factor k, (let k be >1, so k is the ratio of a distance in the larger figure to the corresponding distance in the smaller one)
First, we calculate for the ratio of the surface areas of the given figures. From the given above, the ratio is equal to 25:16
Then, we calculate for the ratio of the perimeters or sides of the figures by getting the square root of the ratio in figure 1.
ratio of perimeter or side = 5:4
The ratio of the volumes of the figures is equal to the cube of the ratio in figure 2.
ratio of volumes = (5:4)³ = 125:64
Using this ratio and the volume of the larger figure,
500 in³/x in³ = 125/64
x in³ = 500×64/125
x in³ = 256 in³
The value of x from the equation is 256. Therefore, the volume of the smaller figure is 256 in³.

Answer:
Variable terms: 4a and 6a
Constant terms: 4 and 11
Step-by-step explanation:
A constant term is one that is NOT multiplied by any variables.
At this level of math, think of constants as terms that are only numbers.
(for example: 1, 68.9, -42, etc.)
Note that a term in « a + bi » form can also be a constant.
A variable term is a one that IS multiplied by a variable.
(for example x, -3y, 8z, etc.)
In question 1, the variable terms are:
4a and 6a because they are multiplied by the variable a
The constant terms are:
4 and 11 because they are simply integers
Note that the constant terms could also be written as -4 and -11 depending on how the operations are viewed (subtracting vs adding a negative)
Equation A matches graph __ because …….I need some help on this
Answer:
The function A is given below as
[tex]y=x^2-6x+8[/tex]Using a graphing tool, we will have the graph be
Hence,
Equation A matches graph 3 because the x-intercepts are on the positive x-axis and it has a y-intercept of 8(on the positive y-axis)
Step 2:
Equation B is given below as
[tex]y=(x-6)(x+8)[/tex]Using the graphing tool, we will have the graph as
Hence,
Equation B matches graph 4
The x-intercepts cuts at the negative x and positive x-axis and the y-intercepts is on the negative y-axis
Step 3:
Equation C is given below as
[tex]y=(x-6)^2+8[/tex]Hence,
Using a graphing calculator, we will have the graph as
Hence,
Equation C matches Graph 1, because its vertex is (6,8) and it has a y-intercept on the positive y-axis
Sales are $500,00 and variable cost are $350,00. What is the contribution margin ratio
If Sales are $500,000 and variable cost are $350,000. The contribution margin ratio is 30%.
What is contribution margin ratio?Contribution margin ratio can be determine or find by substracting or deducting the variables cost form the sales and then dividing it by the sales.
Now let find the contribution margin ratio using this formula
Contribution margin ratio = Sales - Variable cost / Sales
Where:
Sales = $500,000
Variable costs = $200,000
Let plug in the formula
Contribution margin ratio = $500,000 - $350,000 / $500,000
Contribution margin ratio = $150,000 / $500,000
Contribution margin ratio = 0.3 × 100
Contribution margin ratio = 30%
Therefore we can conclude that 30% is the contribution margin ratio .

Solution:
Given the figure below:
To solve for the missing angles,
Step 1: Solve for c.
The sum of the interior angles of a triangle equals 180 degrees.
Thus,
[tex]\begin{gathered} 48+58+c=180(sum\text{ of interior angles in a triangle\rparen} \\ \Rightarrow106+c=180 \\ subtract\text{ 106 from both sides,} \\ 106-106+c=180-106 \\ \Rightarrow c=74\degree \end{gathered}[/tex]Step 2: Solve for d.
The sum of angles on a straight line gives 180 degrees.
[tex]\begin{gathered} 58+d=180\text{ \lparen sum of angles on a straight line\rparen} \\ subtract\text{ 58 from both sides,} \\ 58-58+d=180-58 \\ \Rightarrow d=122\degree \end{gathered}[/tex]Step 3: Solve for a.

The number of $1 loonies are 63 and the number of $2 coins are 189
Let x be the number of $1 loonies and y be the number of $2 coins.
A bank deposit slip shows a total of $441 in $1 loonies and $2 coins.
so, we get an equation,
x + 2y = 441 .................(1)
The number of $2 coins was 3 times the number of $1 loonies.
so, we get an equation,
y = 3x .............(2)
Substitute the above value of in equation (1),
x + 2(3x) = 441
x + 6x = 441
7x = 441
x = 63
Substitute above value of x in equation (2),

Is (A − B) − C = (A − C) − B exists equivalent?Given: (A − B) − C = (A − C) − B.
First, we will attempt to show [tex]$A-(B-C) \subseteq(A-C)-C$[/tex]. Let [tex]$x \in A-(B-C)$[/tex]. Then [tex]$x \in A$[/tex] and [tex]$x \notin(B-C)$[/tex].

We have that [tex]$x \in A \wedge(x \notin B \vee x \in C)$[/tex].
Then we have that [tex]$(x \in A \wedge x \notin B) \vee(x \in A \wedge x \in C)$[/tex].
So by definition of [tex]$\cup$[/tex] and [tex]$\cap$[/tex], we have [tex]$x \in(A-B) \cup(x \in(A \cap C))[/tex].
I can see a contradiction here in that LHS says x ∈ C but the RHS says x ∉ C.
For example, as longer as [tex]$C \neq 0$[/tex]. Let A = 4, B = 2, C = 1.
Then A - (B - C) = 4 - (2 - 1) = 4 - 1 = 3

Answer:
To find the domain of the function f(x)=tanx restricted so that its inverse function exists
we know that,
Since the range of tan inverse x is (-π/2, π/2), the answer should lie in this interval. Assume that y = tan -1 x. Then by the definition of inverse tan, tan y = x. The value of y in the interval (-π/2, π/2) that satisfies the equation tan y = x .
The domain of tanx is restricted to (-π/2, π/2). The range of tanx is always real numbers.
we get that,
The domain of f(x)=tanx is restricted to (-π/2, π/2) so that the inverse function exists. This means that all functional values of f(x)=tan^-1 x are on the interval (-π/2, π/2).
Marian purchased a home valued at $465,000. She purchased homeowner insurance for 75% of the value of the home. If the annual premium on the policyhundred-dollar unit, how much did she pay to the nearest whole cent)?$2,875.50$2,695.00$2,580.75$3,050.74None of these choices are correct.
Ok, so
Marian purchased a home valued at $465,000. If She purchased homeowner insurance for 75% of the value of the home, she paid:
$(465,000)*(75) / (100)
$348,750.
Now, we know that the annual premium on the policy was $0.74 per hundred-dollar unit. Then, this is:
0.74/100 dollar unit.
And, if we multiply, we obtain:
$348,750 * (0.74/100) = $2,580.75
Therefore, she paid $2,580.75
